Introduction
The VERA20 loudspeaker is equipped with two 10” chassis for the low-mid frequencies and
a waveguide with a 1.4” mid-high compression driver. Compared with typical double 8”sys-
tems, the VERA20‘s two 10” drivers are capable of reproducing up to 6dB more output in the
low-mid frequency range with lower distortion.
Thanks to the loudspeaker’s width (only 60 cm / 23.62inches) and height (28cm / 11.02inches),
vertical arrays of up to 24 elements may be constructed.
The newly developed 1.4” compression driver and waveguide provides smooth and accurate
midrange performance for natural vocal and music reproduction. The low frequency crosso-
ver point around 1kHz guarantees precise and uniform coverage even in the sensitive transi-
tion range. The extraordinarily fast transient response ensures that high frequency reproduc-
tion is detailed and crisp.
The VERA20 implements an outstandingly innovative rigging hardware, allowing straightfor-
ward, fast and cost-efficient setup and dismounting by just one technician. A special feature
is logarithmic scaling of the intermediate angles between angles. This allows for angle adjust-
ment of less than one degree to achieve more accurate directivity of upper array elements
over longer distances.

aker may only be used by trained and qualified personnel.
WARNING
WARNING
WARNING
NOTE
NOTE
Please adhere to the following safety instructions to avoid risks when operating loudspeakers.
Note the operating modes described in this operating manual. Other uses are not permis-
sible.
Damage caused by improper use is not covered by TWAMBO.
Loudspeakers generate an electromagnetic field. Persons with pacemakers are not permit-
ted to remain in the immediate vicinity of loudspeakers as the electromagnetic fields can
cause pacemakers to malfunction.
When working with heavy loads exceeding 20 kg (44 lbs.), use suitable aids (dollies, hoisting
slings, etc.). Multiple persons may be required depending on the situation.
Ensure that the units are in a stable position and are firmly attached. A falling loudspeaker can
result in serious personal injury and property damage.
When using and assembling TW AUDiO loudspeakers, only use materials specified by
TW AUDiO. These tasks must be performed by qualified personnel. Adhere to the applicable
safety regulations.
When setting up loudspeakers, ensure that they are not exposed to the following ambient
conditions:
• Direct sunlight
• Humidity
• Jolting
• Dust
Keep away from the immediate vicinity of loudspeakers that are operated at high sound pres-
sure levels. These loudspeaker systems are capable of endangering your health. Sound levels
beginning as low as approximately 90dBSPL can lead to long-term hearing impairment.
Avoid:
• Feedback
• Distorted signals (clipping) and
• Peaks resulting from switching on devices, plugging in devices or unplugging devices during
operation.
Such signals can lead to loudspeaker overload and ultimately to loudspeaker failure.

WARNING
NOTE
NOTE
Ensure that the loudspeaker is not exposed to permanent thermal overloads. Thermal over-
loads may cause a fire and result in serious personal injury and property damage.
Note that TWAMBO does not provide a warranty for damage that can be attributed to this type
of overload and therefore cannot be held liable for any secondary damage.
A permanent magnetic field is present in the immediate vicinity of loudspeakers. Ensure that
objects which react sensitively to magnetic fields are not located in the immediate vicinity of
the loudspeaker. In particular, this applies to magnetic storage media, magnetic stripe cards
such as debit cards and CRT displays. A distance of approximately one meter is sufficient to
avoid damage.
Check loudspeakers and accessory parts regularly for visible wear. This is essential to ensure
continuing fault-free operation. Worn parts should be replaced immediately. Spare parts are
available from TWAUDiO.

specification refers to horizontal coverage. Check the rear rigging to identify the VERA20 vari-
ant.
The factory installed horn flange type is marked on the VERA20’s rear rigging. Depending on
your application, it may be advantageous to change the horn flange. In this case, the identifi-
cation mark on the rear rigging should also be changed. The factory marking can be removed
using acetone.

4.2 Rigging VERA20
VERA20 series line arrays can include VERA20 and/or VERAS32 loudspeakers.
WARNING
NOTE
Note that the VERA20 loudspeakers are mechanically connected. This is done via the quick
and easy 3-point rigging.
Also note that the VERA S32 loudspeakers are mechanically connected via 4-point rigging.
Please refer to the VERARF600, SFV20 and GSP20 manuals for operating modes and set-up
options.
EASE Focus simulation software can be used to plan VERA20 line arrays. EASEFocus is avai-
lable as a free download from the TW AUDiO website at www.twaudio.com.
TIP
Make sure that all system structures are located on a firm, level surface and that the surface
can bear the total weight!
Make sure the speakers are securely fastened to prevent personal injury and property damage.
Secure stacked loudspeakers properly so that they can be tipped by 10° in any direction
without toppling.
TW AUDiO recommends using only the accessories specified by TWAUDiO for securing and
mounting loudspeakers.

4.3 Exchanging the horn flanges
Depending on the product version, the loudspeaker is shipped with either 80° or 120° horn
flanges (see chapter 2.2) installed. For applications that require a different horizontal coverage,
it may be advantageous to change the horn flanges. To do so, proceed as follows.
1. Place the VERA20 loudspeaker on its back, with the speaker grille facing up. The rear
rigging lever must be opened. Make sure to place the speaker on a clean, non-slip-
pery surface. To secure the speaker against lifting and slipping, ask a second person for
assistance.
2. To remove the speaker grille a TX25 Torx wrench is required. Use it to remove the four
mounting screws on the left and right side of the speaker enclosure.
3. Loosen the two screws on each horn flange.
4. Carefully pull the horn flanges upwards.
5. Carefully insert the new horn flanges. Screw them to the enclosure.
6. Reattach the front grill and screw it tight.
7. Change the marking of the installed horn flanges on the rear rigging.
NOTE Take care not to damage the chassis with the screws.
4.4 Operation
Operation of the VERA20 loudspeaker requires a DSP-Controller. For this purpose, only pre-
sets developed by TW AUDiO are recommended. The TW AUDiO system racks are ideally
suited for this purpose.
Please note the technical data in section 3.1 on page 9.
NOTE
NOTE
Make sure that the amplifier’s specifications meet the requirements. Using an amplifier that
doesn’t meet the specifications can destroy the loudspeaker.
Before connecting the loudspeaker to the amplifier, ensure that the right preset has been
loaded.
Using a wrong, out dated or a preset not provided by TWAUDiO can lead to destruction of
the speaker.

4.5 Connecting cables
The pin connections of the VERA20 loudspeaker can be found in section 3.2 (“Connection dia-
gram”) on page 9.
The internal wiring of the VERA20 loudspeaker allows for parallel connection of multiple
loudspeaker units.
NOTE
To create a cable connection with an amplifier rack from TW AUDiO, proceed as follows.
Ensure that the cable cross sectional area is sufficient (at least 1.5 mm²) to avoid power losses.
TW AUDiO recommends using the loudspeaker cables available from TW AUDiO.
When connecting the cables to the loudspeaker, ensure that polarity (+/-) and pin assignment
(1/2) are correct. Incorrect connection can lead to a significant change in the loudspeaker’s
sound characteristics and may damage the driver.
Please note that parallel connections will decrease the total impedance of your loudspeaker
configuration.
The total impedance and the resulting power of the speaker configuration must match the
output power of the amplifier.

5. Transport and Storage
To enable a single person to transport up to six VERA20 loudspeakers, TW AUDiO recom-
mends using the VERA DLV20.
NOTE
Due to the VERA20 loudspeaker weighing over 20 kg [44 lbs.], two persons are required to
handle and transport the unit.
• VERA DLV20 (dolly)
• CoverV20 (protective cover)
When transporting and storing the unit, it is important to ensure that the surface and front
grill of the loudspeaker are not damaged. Moisture can penetrate through exposed wood
surfaces and cause the wood to swell. A bent or broken front grill will no longer adequately
protect the sensitive speaker membranes.
In addition, appreciable dust deposits may considerably impair the functionality of a loudspe-
aker membrane. For this reason, the loudspeakers should be transported and stored in a
safe, careful, dry and largely dust-free manner.
The following accessory parts for transport and storage are available from TW AUDiO:
The original packaging is unsuitable as permanent storage and transport packaging.
